Ayatollah Ali Khamenei rejected President Trump's demand for unconditional surrender, as Iranians jammed the highways out of Tehran.

President Trump approved attack plans on Iran Tuesday night, but did not make a final decision on whether to strike the country and formally join Israel's air campaign, a senior intelligence source and a Defense Department official told CBS News.

Israel said it had struck uranium enrichment sites in Iran after the two countries launched another barrage of missiles at each other overnight.
